Choosing the Right Fertilizer
March 2, 2025
All different types of fertilizers are designed with a common goal: to provide essential nutrients for plant life. They replenish all the elements lost in the soil due to previous crops and add to the existing nutrients in the soil, while also helping to improve plant growth and protect them from many diseases. However, with so many different types of fertilizers on the market, finding the ideal type for your plants can be a challenge.
To choose the best fertilizer, you should select a combination that provides the necessary nutrients for your plants and garden. For this selection, you need to consider the type of plants and their growth rate. You can use this information to help choose a combination of nutrients that will fertilize your plants at the right time without causing starvation or overfeeding. Fertilizers fall into different categories (including natural or synthetic), so when reviewing your options, if you are looking for a specific type, you need to be careful about which one you choose. Keep in mind that the choice of fertilizer type and the amount used is not the same for everyone; different plants have different nutritional needs, so you should know that cactus fertilizer is not a suitable choice for ferns.
Types of Fertilizers
There are two main types of fertilizers that you can choose from based on what you are looking for and the needs of your plants: organic and inorganic fertilizers. While all fertilizers fall into these two main categories, you should know that the levels of nutrients can vary, and there may be other subgroups as well. When deciding whether to choose an organic or mineral fertilizer, you should analyze your own desires and the needs of your plants. Are you looking for a fertilizer that promotes long-term growth? Do you want to enrich your plants with nutrients? In this case, an organic fertilizer may be the best choice. These types of fertilizers are often made from animal manure or compost, and for this reason, they cannot guarantee a specific amount of a particular plant nutrient. In fact, these fertilizers fall into the category of slow-release fertilizers and help with the long-term growth of plants, even improving soil conditions. Another advantage of organic fertilizers is that with some basic facilities, you can easily create a homemade organic fertilizer to help your garden.
However, if you are looking for a specific set of nutrients and need quick, short-term growth, you should choose an inorganic fertilizer. Since these materials are made from chemicals that contain nutrients for plants, they can better specify not only the type of nutrient received but also the amount; chemical fertilizers are excellent for rapid growth and targeting the specific needs of each plant.
Different Forms of Fertilizers
In addition to categorizing contents, fertilizers can also be categorized into different groups based on their form (powder, granular, and liquid), so you should choose the best form for your plant. Your choice of type can often vary depending on how quickly you need it or how long you want it to take effect.
Solid fertilizers in granular form usually have the slowest performance because they are spread on the soil surface and enter the soil over time with watering. Powder fertilizers are also spread on the surface, but they penetrate the soil faster when water is added. Liquid fertilizers often act the fastest because they are used in a similar way to watering. Since they have nothing to break down or absorb, nutrients act slightly faster than solid fertilizers (although liquid fertilizers do not last long in the soil). Whenever you fertilize your plant, be sure to follow the instructions for the best way to meet your plant’s needs; this may include the amount to use, the frequency of use, and whether further dilution is needed. Over-fertilization can also be harmful, but the right amount will help your plant grow to its full potential.
Choosing the Right Fertilizer
How to choose the best fertilizer for your garden and yard can be a simple process, and you don’t always have to limit yourself to one type of fertilizer. For example, you can start your vegetable garden by adding a synthetic fertilizer rich in nitrogen and then fertilize your crops with compost or chemical fertilizers in the middle of the season. Although plant fertilizers are not very effective in vegetable gardens, they are a good choice when combined with chemical fertilizers for gardens and fruit trees. When you need a fertilizer that can be easily used after planting, synthetic fertilizers work well to boost growth without interfering with soil function. A large vegetable garden benefits from early use of a slow-release solid fertilizer rich in nitrogen before transplanting seedlings or planting seeds. Chemical and commercial organic fertilizers are good choices for orchid collections, houseplants, roses, and any specific plants or small crop plantings.
Compost should be added to the soil before planting. This organic fertilizer is best for long-term soil improvement. Most vegetables are planted annually in a garden, which reduces the nitrogen in the soil. Soil nutrients must be replenished after each harvest, which is why adding compost annually makes it an ideal fertilizer for edible crops. Compost can be used in the soil in new greenhouses at planting time or applied as a second stage of fertilization for flowers and food crops during the growing season. Mulch also serves as a final application for flower beds and ornamental plants; this fertilizer should be used in spring or fall and added once again, slowly breaking down into a slow-release fertilizer. Some natural mulches, such as straw or decomposed leaves, can work in vegetable gardens, but because they decompose more slowly than compost, they do not meet the annual nitrogen needs of most plants.
What to Consider When Choosing Fertilizer?
Not all plants react the same way to a type of fertilizer. It is important to know that each fertilizer contains a different combination, meaning they do not solve all problems. You should also know that the soil in one area may not react to fertilizer the same way as soil in another area, even if the soil type is the same. The best way to choose the best fertilizer for any garden is to conduct a soil test. You can start by contacting your local agricultural cooperative office or a specialist to help with a scientific analysis of your garden soil. They can determine nutrient deficiencies or essential elements in the soil composition, pH levels, and overall health or any diseases it may have.
Choose a fertilizer that can meet the pH level of your soil.
For example, if your garden soil is not acidic enough for the plants you like to grow, consider using an acidic combination to fill the nutrient deficiency.
Choose a combination of nutrients based on your needs.
If your garden plants are suffering from brown leaves, a higher nitrogen content in the chosen fertilizer, such as urea, may help the green color flourish. However, if your soil needs protection against drought, using potassium fertilizers is a better choice.
